i-Specification of Lettersiatent. Patented 1 11 '13, 1915. I i ,Appiicaticn m July 14,1913. S eIia1NoL7 79fi72 i ticularity, in the Figs. 5, 6 and 7 already referred to I Asmy invention consists ofanumber of units, ea c h complete 'in itself, although all possessing certain vinter-'dependent func- I H tions, I will describe their constructions and operations seriatim, in order that the work ing'oflmyj device asa whole, may be best understood.- Y Y i d I Willtake up first the paper-controlling unit. The humeral 10 represents a; back plate upon which the several units are mounted. Secured to this plate are, two

vertical side plates '11 and 12' and secured to the side plate 11, is a clockmovement is which has a Winding arbor 15, said arbor extending through said movement 14; and supporting atympan roll 15 concentric therewith the end of the arbor being supported in bearing" in the side plate 12.

This tympan roll is caused to rotate at a constant, predetermined, speed by the above roll 15 and tangent thereto, is a ten- Parallel with sion roll 16 mounted on an arbor 17, which is'constrained to move vertically by two slots 1n the side plates 11 and 12 respectively,"

in which the arbor 17 is mounted. The arbor '17 is forced downwardby compression spr1ngs-20','th'ese springs being retained in position by caps 21'and 22. Turning in bearings in the side plates 11 'andl 2 is-a paper, and a take;i 1proll"26.' Said roll '25 turns freely, while the roll 26is provided with any'suitable" friction drive (not 'let-ofi'roll' 25 which carries a ribbon of p shown), whichfltends to impart to the said roll a surface speed slightly greater than that'of the ,tympan roll 15. By means of the above described construction, the record paper, after leaving theletpfi' roll 25, will beheld tightly against the surface of the tympan roll throughout-its arc of contact;

I will now describe theconstruction ofth' 'engine recording units. There are two a of. these, identical in" construction and operation, one belngactive when the englnels turning ahead, andthe otherwhen the engine is turning astern' v Fig. 9 ,shows dlagrammatically a device embodying means for indicating speed both ahead'and astern. The operation of both is the same and:it is, therefore, deemed necessary to describe but one.

member 30 which is connected with the steamsupply'bya pipe 31. This member-30 Suitably fitted in fthei ."cylinde'r 3O isv the piston'29having a piston rod .32 which is.

I I connected to "a vertical, flexible member 33.

Unsaid member 33 is'a' 3.5 pivoted at 34 which connectswith an arm. v36 which is supported by a parallel motion of the, well known type used in ordinary steam indicators, by means of. which a" stylus 36? mounted at the {extremity of the arm' 36 is caused to move in a line parallehwiththe axis of. the tympan' cylinder and tangent to the periphery of the same, The member 33 I isretained in'pOsitiOnlateraIIyZby four ful- 1 cr ms37',"3s,' 39 and 40 which are adapted to adjust vertically by means of aright and left hand screw {l1 "controlled l by a thumb 7 screw 42.1 The indicator arm 43 which is 10- cated in the rear of the R; M. dialis con- *1 thefpipe 31 againstthe piston 29the mem-' nected with the member bya backwardly ofi'setlink 4A. By thi's constructiono it will beseen that when {steam is admitted through -bel'; 4cq=;willbe caused, to move across the graduated scale located. beneath it whereby the speed of the engine. can be readily seen at a glance. fiCentral' with another dial 45; are. two indicatorsffi and 47. 'By*referring 4 to the Figs; Sand 4, the" operation of these can be readily understood, By a link 48 an arm 49 is connectedwithfthe -iabove jnientioned arm a 36.: This a ctuates aquadrant' 50 i f which. meshes with} the pinion;51 which in quadrant 54cwhich-i's actuated by the 'corre-r i. spending astern mechanism which, has been.
